Properties of Gromov-Witten invariants defined via global Kuranishi charts
Amanda Hirschi
Using the global Kuranishi charts constructed in \cite{HS22}, we define gravitational descendants and equivariant Gromov-Witten invariants for general symplectic manifolds. We prov…

On Donaldson's 4-6 question
Amanda Hirschi, Luya Wang
We prove that the examples by Smith and McMullen-Taubes provide infinitely many counterexamples to one direction of Donaldson's 4-6 question and the closely related Stabilising Con…

Infinitely many monotone Lagrangian tori in higher projective spaces
Soham Chanda, Amanda Hirschi, Luya Wang
Vianna constructed infinitely many exotic Lagrangian tori in the complex projective plane. We lift these tori to higher-dimensional projective spaces and show that they remain non-…
